What is the Chinese name of this compound?
This compound is called "** mercury paste **". Mercury paste is an alloy of mercury and other metals.
Take the "Tiangong Kaiwu" as an example, many of which describe mercury paste. Mercury is active and can be combined with many metals, resulting in mercury paste with specific properties.
"Tiangong Kaiwu" says: "Where cinnabar, mercury, and silver vermilion are originally the same thing, so those with different names are divided into coarse, old and tender. Good cinnabar, every time it is exposed to fire and mercury, it will be discarded and donated. If the mercury has risen to vermilion, take it into coptis, chalk, minced beans, etc., and grind it in a stone trough. When used, fill it with copper or silverware, and its color will gradually darken. Pour it out and wash it with water, and it will become white as before. This is mercury paste. "This paragraph details the preparation method of mercury paste, which is to smelt mercury from cinnabar, and then grind it with specific substances to form mercury paste.
Mercury paste has a wide range of uses. In ancient metallurgy, it can help extract gold and silver. Because mercury can form mercury paste with gold and silver, after heating and other methods, the mercury will evaporate, leaving the pure quality of gold and silver. And mercury paste is also used in medicine, alchemy and other fields. However, mercury paste contains mercury, which is not small in toxicity, so use it with caution. In ancient times, alchemists often used mercury paste improperly, causing mercury poisoning.
In summary, although mercury paste has its functions in ancient craftsmanship, medicine, etc., its toxicity should not be underestimated, which is actually a combination of advantages and disadvantages.
What are its physical properties?
A strange stone, with strong, moist, strange and elegant physical properties.
It is strong, the stone is dense, and there is a sound when it is knocked. It is like the chirping of gold and stone, which can be honed over time and eroded by wind and rain without damage. It shows that its texture is solid, and it can bear the weight of thousands of tons without cracking. It has a body like iron, and it stands firmly in the world.
It is moist, the surface is delicate and smooth, as warm as suet jade, the tentacles are warm, and there seems to be a layer of radiant luster flowing on it. Just like the dew of spring morning, it condenses on the stone surface, but it does not slip off. The view makes people feel love and pity. This is the moisturization given by the precipitation of time.
It is also strange, with a strange shape, or like a bird spreading its wings to fly, or like a beast lying down about to get up, or the elegant posture of an immortal-like person, which is ingenious and cannot be carved by human hands. The texture is also unique, or winding like mountains and rivers, or dense like a list of stars, each place contains the wonders of nature, which amazes the wonders of creation.
Its elegance is also placed on the case table, adding a room of elegance. Looking at it can lead to meditation, as if you can have a dialogue with the ancients and feel the precipitation of a thousand-year-old culture. In the hustle and bustle of the world, he keeps a quiet, like a humble gentleman, with his silent state, conveying the elegant rhyme, making the viewer's heart also quiet and gradually enter the realm of detachment.
What are its chemical properties?
Mercury is soft and agile, liquid at room temperature, like silver beads flowing, shining brightly. Its chemical properties are unique and quite wonderful.
Mercury is relatively moderately active and can be fused with many metals to form amalgam. As in the past when alchemy was used, mercury was often co-refined with lead, tin, etc. Mercury can be closely combined with them, as if a match made in heaven, forming amalgam of different shapes. During this process, the characteristics of mercury are fully demonstrated, and its fusion power is like a wonderful hand of creation.
Mercury can also react with oxygen. Under heating conditions, mercury will slowly combine with oxygen, just like a quiet and quiet blend, forming red mercury oxide. This change is like a picture that quietly unfolds, witnessing the unfolding of the chemical properties of mercury. Mercury oxide can be decomposed when further heated, returning to mercury and oxygen, and changing in this cycle, as if the mystery of nature is quietly interpreted in it.
Mercury is in acids, and when it meets nitric acid, it will react, just like a friend meeting, triggering a wonderful chemical wave. Mercury can dissolve in nitric acid, forming mercury nitrate and other substances. With the escape of bubbles, the change of solution shows the unique chemical activity of mercury.
However, mercury has one property that cannot be ignored, and its compounds are many toxic. When it interacts with other substances to form various mercury compounds, these compounds are like hidden dangers, and if accidentally contacted or ingested, they will cause harm to life. This property warns everyone that when using mercury and its related substances, they should be extremely cautious and must not be taken lightly to avoid its harm.
The chemical properties of mercury not only contain wonderful changes, but also hidden potential risks. It is like a double-edged sword. In the exploration and application, it is necessary to gain insight into its nature and grasp it well in order to seek advantages and avoid disadvantages and appreciate the wonders and mysteries of the chemical world.
In which fields is this compound used?
This compound is useful in all fields. In the field of engineering, it can increase the firmness of the utensils and make the equipment durable. For example, when a sword is forged, it is combined with this compound, and the blade is strong and soft, and the iron is like mud, which can be used as a sharp weapon of the gods.
In the world of medicine, it also has special effects. It can be used as medicine to adjust yin and yang, qi and blood, and heal various diseases. Ancient healers often used the compound to prepare pill ointment powder to save the diseases of all people.
In the matter of farming mulberry, it is also indispensable. Applying this substance to the fields can fertilize the soil and promote the harvest of five grains. Make the crops lush, the fruits are fruitful, and the people's clothing and food are protected.
In the cause of construction, it can be used to strengthen civil engineering. When building a pavilion or palace, this compound is added to make the wall strong and the house will not collapse for a long time. Such as the construction of the Great Wall, the bricks and stones are bonded together or with this compound, so that they can stand for thousands of years without falling.
In the process of craftsmanship, such as firing ceramics, making gold and silver utensils, etc., the compound can help craftsmen to be ingenious. Ceramics are glazed with this object, which is bright in color and warm in texture; gold and silver utensils are tempered by it, which is even more exquisite.
All these things can be seen in the various fields of the world, whether bright or dark, are of great use, and are closely related to various matters of people's livelihood and are indispensable.
What is its preparation method?
The method of making utensils is quite exquisite. According to the "Tiangong Kaiwu", each utensil has its own method.
All the genus of casting tripods, want to have both shape and spirit, and the system of casting is the first. Choose the soil that must be fine, choose the one that is pure in quality and soft in nature, sieve it to be fine, and knead it with water and other things like dough, and beat it repeatedly to make the soil even. Then, according to the shape of the casting, shape it into a mold embryo, and carve the texture, striving to be realistic. When the mold embryo is slightly dry, apply a special material, which can make the casting surface smooth and prevent adhesion.
When smelting, the choice of metal is also important. The best copper, iron and other ores are mined, and after many refinements, their impurities are removed to make the quality pure and strong. In the furnace, the accumulation of fuel and the blast of wind make the fire fierce and warm. When the metal is melted into a liquid, pour it into the finished mold. When the pour is steady and even, so that the liquid metal fills all parts of the mold without omission.
As for the forging tool, the material is selected firmly, and it is struck repeatedly with a sledgehammer. At first, the force should be heavy, so that the metal can be extended and its pores removed. Then, it is trimmed with the shape, and the surface of the device is smooth and the edges and corners are clear. In the meantime, the mastery of the heat is particularly critical. If the fire is too strong, the metal will be brittle, and if the fire is not enough, it will be difficult to form. It is necessary to observe its color, observe it with experience, and adjust the heat in a timely manner.
Another example is pottery-making utensils. The clay is selected in a specific place, washed and precipitated, and its coarse sand and gravel are removed. After making the billet tire, it can be dried in the shade, or baked in the kiln. When firing in the kiln, the temperature is precisely controlled, and different temperatures are used at different stages. In the early stage, the small fire is slow to dry, so that the moisture of the billet tire is gradually lost; in the middle stage, the fire is fierce, so that the pottery is dense; in the later stage, the temperature is cooled slowly to prevent bursting. In this way, exquisite pottery can be obtained.
All the methods of making utensils are condensed with the wisdom of the ancients. The process is complicated, and the step by step is
